[…] The spirit that I have seen
The Ghost always seems to be associated with Hamlet's is-he-or-isn't-he insanity. Here, Hamlet is concerned that the Ghost may be "the devil" and is trying to tempt him to murder Claudius without just cause. What's interesting to us about this passage is the way Hamlet (who is alone on stage at this point) wonders if being depressed has left him vulnerable to evil—which is maybe one more reason to drag his feet before committing murder.

Polonius is convinced that Hamlet is "far gone, far gone" in his love for Ophelia. But—sorry, Polonius—we think it's more likely that Hamlet is likely making a naughty joke at Polonius's expense: a "fishmonger" is slang for "pimp." I.e., Hamlet knows that Polonius is basically pimping out his daughter to get at Hamlet.

HAMLET I am but mad north-north-west: when the wind is
First, this seems to be Hamlet telling Rosencrantz and Guildenstern that he knows exactly what they're up to: spying on him. But we also included this as a little lesson in how things get lost in translation. "Handsaw" is almost certainly a corruption of "heronshaw," i.e. a heron—which sounds a lot less crazy than comparing a bird to a carpentry tool.
